Full official abstract

The FAA is adopting a new airworthiness directive (AD) for Teledyne Continental Motors (TCM) O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 series reciprocating engines with TCM EQ3 cylinders installed. This AD requires initial and repetitive visual inspections of TCM EQ3 cylinders for cracks. This AD also requires removal of all EQ3 cylinders as terminating action to the repetitive visual inspections. This AD results from reports of 35 EQ3 cylinders found cracked. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder head, possible engine failure, and fire in the engine compartment.
